Re: Correct process of removing volume from Aggregate when no longer needed?

You got pretty much everything covered. but there should be some slight change in order.

Step 2 should be on Destinatin 

Step 6 should be on Source 

quiesce, break, [delete] & release

That mean, step 6 should be just after your step-2

Once remove the snapvault/snapmirror relationship completly, (no relationship reporting between volume from sourse as well as destination cluster)

then only i'll proceed with LUN/volume unmaping, offline and delete process.

This link might help you.
